WILLIAM FRAZIER ROSS, OF DAVENPORT, IOWA.

IMPROVEMENT EN MAGAZINESTOVES.

Specification forming part of Letters Patent No. 156,82h, dated November 10, 1874; application filed January 20, 1873.

of, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification, in which drawing Figure 1 is a perspective view. Fig. 2 is a central vertical section. Fig. 3 is a front elevation, with a portion of front broken to show the interior construction and arrangement.

This invention relates to that class of heating-stoves designed particularly for burning bituminous coal. It is intended to be used without any guard between it and the floor, mantel, partition, or Wood-work near to which, in any direction, it may be placed, and it presents in these respects, and in its efficient power of combustion, a safe and desirable stove for common and household use; and the novelty in it consists more particularly in providing for a complete and thorough circulation of air through the spaces or chambers in the base, rear, and top, whereby not only is the radiation of heat most effectually prevented, but a conduit provided, whereby the foul air is led oil from the apartment in which the stove is placed, and fed down upon the burning fuel to promote combustion; and it further consists in adapting the chambers at the bottom and top, either or both, to supply steam or moisture to the current of air flowing through them and the passage in rear of the stove, and down upon the fire-bed; and it consists, further, in so constructing the portions of the stove about the top of the fuelmagazine, and so circulating currents of moistened air over and about said magazine, as to prevent condensation and deposit of tar thereon or thereupon 5 and it finally consists in an outstanding or heating stove jacketed pn all sides excepting the outwardlyprojecting or curved front, so that, while a very large and effective front radiating-surface is afforded, the peculiar shape and construction of the said stove admits of its being safely placed in any position in the room in respect to the floor, walls, partitions, or mantels, 85c.

In the accompanying drawings, A represents the semicircular front casing of my stove, in which is arranged, centrally, a fuel-reservoir, B, which is preferably semicircular in front, to conform to the particular shape of the external casing, and in this semicircular portion of the magazine there is an air space or conduit, 0, extending from the upper chamber D, and connecting it with the combustion-chamber immediately below the fuel-reservoir. E denotes the grate, which may be of any ordinary or usual construction adapted to this class of heaters. Immediately below this is the ashpit F,'to which access is had by door G. Fuel is fed to the magazine through the door H over its top, to which access is had through door I in the front casing of the stove. The products of combustion pass from the combustion-chamber proper, K, into the passage or chamber L, and thence to exit-pipe M.

While the front casing of my stove is semicircular, the back or rear part is plain or flat. In the base, rear, and upper part of the stove are provided chambers or spaces N, O, and P. These are made or formed between the outer and rear casing Q, bottom plate Q, and top plate Q, and the inner plates R, R, and 0. These several chambers or spaces constitute, in fact, one continuous flue, since they communicate freely with each other. The diaphragm or plate 0 in the upper part of the stove extends inwardly and across the top of chamber or space 0, and is here provided with numerous openings or apertures 0; but this special form of construction has now been adopted for convenience more than for purpose of showing essential points in present invention.

Air from the apartment in which the stove is placed may be admitted into chamber N by pipe S, which is provided with a damper, s. This pipe may on occasion be connected with a pipe leading outside the house or building, to bring in fresh air to the chamber or spaces about the stove, as aforesaid. Likewise, an aperture, T, in the front of the stove may be used to admit the foul air of the room into this chamber or space. The pipe S extends up into said chamber N a little distance above its bottom. This is done because said cham ber may be used sometimes to hold water. In like manner the pipe V in chamber P extends above the bottom floor 0 of that chamber, and the partition in the rear is extended above the plate 0 into chamber P, to complete the adaptation of chamber P for holding water.

Into either or both of these chambers I may introduce water by any convenient method or means, not now more fully illustrated than by making the top plate of the stove removable, as indicated in Fig. 1, or by providing the aperture at T. The use of this aperture as an induct I have above set out; the use I now mention is also an essential reason for havin g it. But I can readily adopt any other cheap, usual, or convenient means for this purpose. The object and use of Water in these chambers is to hydrate, in some measure, the air, so as to prevent, by its circulation through chamber D and passage 0, and over top of magazine, any deposit or accumulation of coal-tar, or the sticky matter arising from the distillation which, in some degree, takes place in the process of combustion of bituminous coal, for the burning of which my stove is more particularly designed.

It will readily be perceived that the water and air chamber P, formed by the double top of the stove, with its pipe V, entirely differs in operation from the ordinary movable hydrating or water pan, which is sometnnes placed in the hot-air chamber of a stove or furnace, because it is a component part of my stove and serves the essential function of preventing the radiation of heat, and also because by means of it the inflowing current of air is led downward toward the point of combustion.

Theinflowin g current of moistened and heated air, descending upon the mass of highly-heated coals, and meeting and commingling with the products of combustion as they arise from the glowing coals, assists materially in making the combustion more perfect and thorough.

By means of a damper, s, and a slide over T, (said slide is not now shown,) or by any other equivalent ways or means, the draft through these chambers or spaces may be regulated, controlled, or cut off at pleasure. If desired, apertures may be made in partition R at r, to be regulated or controlled by damper.

My stove, as thus made and used, is designed to heat only from the front. It can be placed in any position in a room with respect to the relation between its rear, top, and bottom to any adjacent wood with almost entire safety from any danger of communicating fire or producing combustion. There is no occasion in using it to place deflecting-shields or metal plates behind, beneath, or above it. In this respect there is no little economyin use of my heater, while in regard to its safety it possesses the most admirable advantages of any heatingstove now on the market or known to the trade.

What I claim as new, and desire to secure by Letters Patent, is

l. In combination with the base, rear, and top chambers, as set forth, a fuel-reservoir, B, having the air space or passage 0 comm unicating with said chambers through chamber or space D, and adapted to operate as set forth.

2. In combination with the heatingstove herein described, the base-chamber N, forming a double bottom to prevent the radiation of heat, and adapted, bymeans of pipe S opening into it through and at a distance above its bottom, for an air and water chamber, substantially as described.

3. The upper water and air chamber P, formed by the double top of the stove, and having pipe V opening outof it at a distance above its bottom, to convey the downward current of air toward the combustion-chamber, the several parts constructed and combined with the stove, as set forth.

4. In the heating-stove herein described, semicircular in front in horizontal cross-section, the combination of the jacketed space at bottom, rear, and top, substantially in the manner and for the purposes set forth.
